Known faults, from the test record

Kia Venga common problems

What fails on the Kia Venga at MOT, which parts are behind it, and how each model year compares. From 46,382 DVSA test records.

Data updated

Quick answer

The Kia Venga's most common MOT problems are bulbs and lamps, ball joints, tyres, recorded in 39.4%, 32.5% and 24.7% of failed tests respectively. By model year, 2019 cars pass most often (88.8%) and 2010 cars least (53.9%), though most of that gap is age. Every figure here is what testers recorded, not what owners reported.

A “common problems” list is usually a forum thread: whoever had the worst day writes the longest post. This one is built the other way, from every Kia Venga that took an MOT last year and what the tester wrote down. It cannot see breakdowns, electrical gremlins or a gearbox that hunts, because the test does not check those. What it can see, it sees across 46,382 cars.

By component

What wears out on a Venga

Failure items grouped by the part behind them, with the share of failed Kia Venga tests recording each. A part can carry several DVSA wordings; they are listed beneath. One failed test often lists several items, so shares do not sum to 100%.

  1. 1.Bulbs and lamps

    39.4% of failed tests

    Filament bulbs simply expire; the cheapest and most avoidable failure on the test, and one of the most recorded.

    • “A lamp missing, inoperative or in the case of a multiple light source more than 1/2 not functioning” — explained16.9%
    • “Stop lamp missing, inoperative or in the case of a multiple light source more than 1/2 not functioning” — explained10.8%
    • “A rear registration plate lamp or light source missing or inoperative in the case of a single lamp or all lamps” — explained3.8%
    • “A headlamp or light source missing, inoperative or more than ½ not functioning in the case of LED” — explained3.4%

    Across all cars, bulbs and lamps failures climb 15-fold between three and fifteen years, peaking at 15+ years. How long bulbs and lamps last

  2. 2.Ball joints

    32.5% of failed tests

    Steering and suspension ball joints wear internally and their dust covers split; excessive play fails.

    • “A steering ball joint with excessive wear or free play” — explained30.5%
    • “A steering ball joint worn to the extent there is a serious risk of detachment” — explained2.0%

    Across all cars, ball joints failures climb 28-fold between three and fifteen years, peaking at 12–14 years. How long ball joints last

  3. 3.Tyres

    24.7% of failed tests

    Tread wears with every mile and sidewalls age and take kerb damage; the legal minimum is 1.6 mm across the central three-quarters.

    • “Tyre tread depth not in accordance with the requirements” — explained8.8%
    • “A tyre cords visible or damaged” — explained5.8%
    • “A tyre seriously damaged” — explained5.2%
    • “A tyre seriously damaged” — explained3.0%

    Across all cars, tyres failures run at a similar rate at every age, because they are replaced on a cycle rather than wearing out with the car. How long tyres last

  4. 4.Suspension bushes

    23.3% of failed tests

    Rubber bushes in arms and links perish and split with age and load; the most recorded suspension item on the test.

    • “A suspension joint dust cover missing or no longer prevents the ingress of dirt etc” — explained11.0%
    • “A suspension joint dust cover missing or no longer prevents the ingress of dirt etc” — explained4.2%
    • “A suspension pin, bush or joint excessively worn” — explained3.3%
    • “A suspension pin, bush or joint excessively worn” — explained3.1%

    Across all cars, suspension bushes failures climb 20-fold between three and fifteen years, peaking at 15+ years. How long suspension bushes last

  5. 5.Wiper blades and washers

    15.3% of failed tests

    Rubber blades harden and split within a year or two; washer jets block and pumps fail.

    • “Windscreen washers not working or not providing sufficient fluid to clear the windscreen” — explained5.6%
    • “Wiper blade missing or obviously not clearing the windscreen” — explained5.1%
    • “Windscreen washers not working or not providing sufficient fluid to clear the windscreen” — explained4.6%

    Across all cars, wiper blades and washers failures run at a similar rate at every age, because they are replaced on a cycle rather than wearing out with the car. How long wiper blades and washers last

  6. 6.Brake pads and shoes

    10.5% of failed tests

    Friction material wears with use; the MOT limit is 1.5 mm and a pad that thin is close to metal on metal.

    • “a brake lining or pad worn below 1.5mm” — explained10.5%

    Across all cars, brake pads and shoes failures run at a similar rate at every age, because they are replaced on a cycle rather than wearing out with the car. How long brake pads and shoes last

  7. 7.Brake discs

    9.0% of failed tests

    Discs thin with each pad set and pit or corrode when lightly used; failure is for significant wear, fracture or insecurity, advisory for surface condition.

    • “Brake disc or drum significantly and obviously worn” — explained5.3%
    • “Brake disc or drum excessively weakened, insecure or fractured” — explained2.1%
    • “Excessive fluctuation in brake effort through each wheel revolution.” — explained1.6%

    Across all cars, brake discs failures climb 3-fold between three and fifteen years, peaking at 12–14 years. How long brake discs last

  8. 8.Parking brake

    6.8% of failed tests

    Cables stretch and seize, rear shoes and adjusters wear; efficiency is measured on the roller tester against the vehicle's weight.

    • “Parking brake efficiency below minimum requirement” — explained5.4%
    • “Parking brake inoperative on one side” — explained1.4%

By registration year

Venga problems by year

MOT pass rate for Kia Venga cars by the year they were first registered, from years with at least 1,000 tests. Every car in a row is the same age, so the rate is raw. Neighbouring years differ by a year of wear — a step of a point or two is age. The step at 2015, up 10.7 points, is larger than wear explains and most likely marks a change in the cars themselves.

201054%
201155%+1.1
201259%+3.6
201362%+3.6
201464%+1.9
201575%+10.7
201679%+4.4
201784%+5.1
201888%+3.4
201989%+1.0

Common questions

What are the most common problems with a Kia Venga?
Going by what fails the MOT, bulbs and lamps (recorded in 39.4% of failed tests), ball joints (recorded in 32.5% of failed tests), and tyres (recorded in 24.7% of failed tests). These are the items testers actually record across 46,382 tests, not reports from owners, so they describe what goes wrong at the point where it has to be fixed.
Which Kia Venga year is the most reliable?
By MOT pass rate, Kia Venga cars registered in 2019 do best at 88.8% and 2010 cars do worst at 53.9%. Most of that ordering is simply age — newer cars pass more — so read the year table for steps larger than a couple of points between neighbouring years; those mark a change in the cars rather than the calendar. The largest such step is at 2015, up 10.7 points on 2014.
Is the Kia Venga reliable?
Adjusted for the age and mileage of the cars tested, the Kia Venga passes 64.3% of MOTs against a national 72.3%. An MOT measures roadworthiness on the day rather than breakdowns or running costs, so this is a reliability measure in the narrow sense: how often the car meets the legal standard, and what stops it.
What should I check when buying a used Kia Venga?
Start with what fails most: bulbs and lamps, ball joints, tyres. Then read the car's own MOT history for advisories carried year to year without repair — the model tells you what to expect, the history tells you whether this owner dealt with it.
